Classification of Lung Neuroendocrine Neoplasms (Lung-NENs) According to WHO 2010 for Gastroenteropancreatic NENs (GEP-NENs) Has Prognostic Relevance and Includes Lung-NETs G3 Abstract #1668

Introduction: The classification of lung neuroendocrine neoplasms (Lung-NENs) according to the WHO classification 2010 for GEP-NENs, including a provisional category for Lung-NET G3 with Ki67 >20%, may have prognostic implications.
Aim(s): The prognostic impact of WHO2010 classification including the NET G3 category was investigated in Lung-NENs.
Materials and methods: 213 surgically resected Lung-NENs from Japan were histopathologically re-evaluated and the data correlated with survival.
